Abstract:  In connection to a conjecture of W. Lü, Q. Li and C. Yang (2014), we prove a result on small function sharing by a power of a meromorphic function with few poles with a derivative of the power. Our results improve a number of known results.
Keywords:  meromorphic function; derivative; small function
Classification MSC:  30D35
